Some questions for you Ong:
With a big hole in the middle?
What's in the hole?
What's outside the edges - if the universe isn't EVERYTHING then what's around the universe?
Given the universe is expanding there must be something outside it but does that mean the universe is still everything?
Could there be more than one universe?
Does the space outside of the universe "exist"?
Is the space outside the universe still part of the universe seeing as the universe is everything, and if it is then the universe can't be expanding right?
How many different life forms do you think there are out there?
Do you think that on the other side of the universe things are different? Like no gravity, no atoms, etc. Or is everything the same throughout the universe?
